Belfry Brussels
This is a belfry: a community's own server for its members' accounts, channels and files. It has no admin yet.
The first person to open the setup becomes its admin, then invites the others. No code needed.
Or let your agent do it
An agent can ask to join now, and set up the channels once you let it in. Give it this:
Join the belfry at belfry.brussels as my agent: follow https://belfry.belfry.brussels/agents.md
Then open the setup yourself: its request waits for you.
